ELECTRICAL BULLETiN.

SPECIFICATION forming part of Letters Patent No. 386,189, dated July 17,1888.

(Ko model.)

To @ZZ whom, it may concern."

Beit known that i, PATRICK B. DELANY, of New York city, New York, acitizen of the United States, have invented a new and use ful ElectricalBulletin, of which the following is a specification.

rlhe object of my invention is to provide a system vfor thedissemination of news, having a central otiice at which all currentmatters of interest are reported, and bulletins located at subscribers7stations and capable of being operated from the central ol'ice toindicate or display to the observer the transmitted information.

ln carrying out my invention I employ a number of wheels arranged inparallel vertical planes, and having the letters ol' the alphabet andsuch other matter as may be desired marked upon their peripheries, and Icontrol these wheels from the central office, through suitabledistributing or selecting apparatus, in such manner as to successivelyoperate each wheel to display the required letter or character. This maybe accomglishcd by the use of either a double or single circuit, and Imay use, as I do by preference, suitable signaling and unison apparatus.All this appears fully l'rom the following` specification.

The accompanying drawings illustrate one practical and efficientembodiment of my invention; but l do not in all respects limit myself tothe specific construction, though the organization shown is in generaloutline the best ol' which l am new aware.

Figure l. is a diagram view illustrating` a central-olitec station andtwo outlying or subseribers7 instruments operated by a double circuit.Fig. 2 is an end View el' so much of the bullet-in apparatus as isnecessary to illus trate the manner ol' operating the wheels and workingthe unison oi' the bulletin-wheel. Fig. f3 is a rear viewot' several oithe bulletinwheels and their actuating apparatus. Fig. i is a diagramview illustrating a single-circuit arrangement for workingthcinstrinnents, and Fig. 5 is a detail View showing the trailerbridging from one segment to another.

Referring to Fig. l, X represents a centraloflicc bulletin displayingthe news, Kaiser dead. Bourse firm."7

Y and respectively indicate so much of a subscribers bulletin as isrequired l'or illustration of the invention; but let it be assumed thatat these stations the bulletin-wheels are at unison, as illustrated, andwill be operated one by one in conjunction with the wheels of thece'ntral-oflice bulletin to display the same item. The operation at thecentral-office bulletin X is the same as that which takes place at thebulletins Y and Z. At the central station the battery MB is connectedwith the stop of each key A and B. The key A is included in a circuit, aa', extending from the key through the operating-magnets C C ofthedistributers of the respective bulletins to ground. Each magnet Chas apivoted armature, C, whose pawl engages the teeth of a drivingratchetswheel, c, fast on a spindle carrying trailer orcircuit-completer, c. which is thus caused to traverse a table, C1", ofinsulated con tacts. Upon each depression of the keyA the trailer c ofevery bulletin in the circuit is caused to pass from one insulatedcontact in its circle to thcnext contact. Thot-able of contacts of eachdistributer or selector may of course contain any desired number ofsegments. l have shown but thirty, and consider these a suflicicntnumber to display upon the bulletin in a concise manner any item that itis desired to transmit. Each distributcr is provided with an or/diuaryEdison worm-unison, U, arranged to permit two tull revolutions ol' itsshalt. The circuit ofthe unison-magnet Uis from the line b through thetrailer, segment a, and unison-magnet, the continuation If ol` this linebeing the main line and leading to the spindle or trailer of the nextdistri buter, and so on to ground. @bviously by manipulati ng the key Aa sufficient number ol'times all the instru merrtsiay be brought tounison withI the trailers c on the unison-segments u. 2y the depressionof the key .i3 the line bi will be completed from the battery MB throughthe various magnets U to ground, and the uuisonstops thrown oii all theinstruments. They will then bein readiness for the reception and displayof any item of news transmitted. rEhe depression of the key A will causethe movement of all the trailers c iroin the unison-segmento to the nextsegment, 7L,connected through the coils of a magnet, H, which serves toremove the unison-stops from the paths of the several bulletin-wheels inthe following manner: rlhe armature h of the magnet H is lOO fast uponan endwise-sliding shaft, I, carrying a number of adjustable collars, i,adjustably secured to the shaft by setscrews, as shown,

one for each wheel, having stops against.V

which vcorresponding projections on the bulletin-wheels abut when thewheels are at unison. This detail of construction is clearly seen inFig. 2. Thebulletin-wheels all being at unison. the unison-stops aresimultaneously removed from all the wheels by the energizing of themagnet H and the consequent endwise shifting ofthe shaft I. Theunison-magnet H is energized when the key B at the central station isdepressed and the trailer is on the cont-act h.

In the drawings I have shown four segments, d ef g, respectivelyconnected. through the magnets D E F G of their bulletinwheels with themain-line wire b2. The trailer is advanced from the segment h to thenext segment, d, upon the depression ofthe key A. By the manipulation ofthe keyv B the magnet D of the first bulletin-wheel may now beintermittently energized and the wheel advanced step by step until theproper letter or character is exposed to view. In like manner all thewheels are operated when the trailerhas been brought upon theirrespective segments. One manner of effecting this progressive movementof the bulletin-wheel is shown in Fig. 2, where D represents the magnet,D its armature, and d the pawl carried thereby and engaging a drivingratchet-wheel on the hub of the bulletinwheel. Duplicate ratchet-wheelsare shown, the teeth of one being placed opposite the spaces ot' theother, and locking dogs or spurs for preventing any excessiveorirregular movement of the wheels may be arranged as illustrated.

The bulletin may be inclosed within a suitable case, K, provided with atransverse aperture covered by a glass, la, through which the matterdisplayed by the bulletin-wheels is read. The distributing devices maybe arranged in a box, L, on the under side of the instrument, or in anyother suitable location, and the entire apparatus mounted upon bracketson the wall in a convenient position to be seen. The sizes of wheels andletters will be adapted in each case to the special purpose and locationof the bulletin; but letters of an inch in height will no doubtvbe foundsufficient for all ordinary purposes. Each of the bulletin-wheels isshown as marked with the letters of the alphabet, and at the end of thealphabet and in the middle is a dot for spacing. In the distributerthirty contacts have been shown, twenty-six being used forletter-wheels, one for the distributer-unison U, one for thebulletin-wheel I unison-magnet H; another, u', for the magnet H', bywhich the unison of the bulletin-wheel is applied, and the remainingone, s, may be connected with a callbell or other signaling device, CB,to indicate when a fresh item ot' news is displayed.

In the drawings each bulletin-wheel is sh own as carried in a pair ofuprights, instead of mounting all the wheels on a common shaft, as mightbe readily done.

By making the stops on the bulletin-wheel unison-shaft adjustable Iprovide for any irregularity of size ot' wheels in manufacture, and forwarping, shrinking, or distortion ol' the wheels while in use.

In the diagram View, Fig. 4, I have shown an organization in which thebulletins are operated on a single circuit. In this arrangement I employone strength of battery to rotate the trailers and an increased strengthof battery to e'ect the movement of the bulletinwheels.

Referring to the drawings, MB and MB2 show two batteries having oppositepoles turned toward the line and split or divided, as shown. Aswitch-lever, S, is centrally pivoted and provided with segmentalcontactpiece t t at each end, which serves to throw a portion ofthe-battery MB to line when the switch is thrown to the left, and aportion of the battery MR2 when the switch is thrown to the right. Theswitch is retained in the central position, when so placed, by an anchoror steadying-spring, T. The circuit in each caseV is from the portion ofthe battery MB' or M B2, through the polarized relay PR, trailer c', thesegment upon which it happens to be resting through the coils of abulletin-wheel or unison magnet, as the case maybe, so wound that itdoes not respond to such impulses,'and thence to the polarized relay andtrailer of the next bulletin, and so on to ground. The trailers havingbeen rotated to the proper segment in each instance, the unisons arethrown oi or the bulletin-wheels rotated or the signaling device soundedby the manipulation ot' either the key B or B', which throws the wholestrength of its battery upon the line. Acurrent of the same polarity asthat last sent for the operation ofthe distributers must in each case betransmitted. The magnets connected in the segment-circuits respond toits impulses. The polarized relays remain ati-est.

It will be noted that in both Figs. 1 and -i the trailers are shown onthe segments near their edges, so that on the next movement the trailermust cross the greater part of the segment upon which it has beenresting. This is for the purpose of allowing a full and ample durationof contact between the segment and trailer while the impulse ol'electricity is passing and is energizing the polarized relay PR to movethe trailer across the segment onto the edge of the adjoining one. Therewould therefore be but little danger of the polarized relay losing itsimpulse and failing to move the trailer at the'mo'ment it was betweenthe two segments; but in order to further guard against such apossibility and to keep always closed that part of the circuit passingthrough the instrument the trailer and segments are so arranged that thetrailer, in passing from one segment to another, bridges and maintainsthe continuity of the circuit, Fig. 5.

So `lar as l am aware, am the first to provide an organization similarto that indicated in Fig. it, in this respect, that the impulses whichoperate the trailer are transmitted through its n1agnet,throngh thetrailer,theseg ment upon which it rests, and the branch circuitconnected with that segment, and thence through a conductor common toall the branch circuits to the next magnet and trailer, and so 011.Obviously such an organization may be used l'or other purposes than thatot' operating bulletitrwheels.

I am aware ot' those iirealarm systems in which numbers indicating thelocation ot the Vre are exposed to View. l am also aware ot that classot'stiock-imlicators in which marketquotations may be read fromcharacters upon the peripheries of rotated wheels; but such syst-cms areobviously not analogous to the in vention herein described, l'or thereason that -the mechanism employed and the general system of operationare materially different from what is herein disclosed, and are notcapable of progressive operation to such an extent as is required todisplay information in the manner above indicated.
